Sejarah
Nitrogen is considered to have been discovered by Scottish physician Daniel Rutherford in 1772, who called it noxious air or fixed air.
It was also studied at about the same time by Carl Wilhelm Scheele, Henry Cavendish and Joseph Priestley.
In 1790 the French chemist Jean-Antoine-Claude Chaptal named the element nitrogen.

Rapid release of nitrogen gas into an enclosed space can displace oxygen, and therefore represents an asphyxiation hazard
